OMP Hobby M4 Helicopter Battery Tray Set

Meh,

If you squeeze them too hard they may brake. One already did. Who designed this? Using gensace batteries the set screws do not secure it right. The flat side of the battery is on the opposite of the set screws. Not only that, trying to secure a tight fit doesn't work to well. TOO Tight! Used double sided velcro with straps instead.

They are a great idea BUT I found them to be easily broken if you squeeze the release a little too hard. Also I am finding them challenging to release and slide out so my personal preference is to leave the tray alone and just use the battery straps to swap batteries. Quality control? Maybe. So that is my method. I believe it could be improved upon.
